 Welcome to the Complementary Formula Calculator

The Formulas for the Calculator's is displayed in the table below!  E = Voltage / I = Amps / P = Watts / R = Ohms / PF = Power Factor / Eff = Efficiency / HP = Horsepower / kVA = Apparent Power

Formula Tables

To Find Direct Current AC/ 1 Phase (115/120) AC/ 1 Phase (208/230/240) AC/ 3 Phase (All Voltages)
Amps When HP is Known
Amps When Kwatts is Known
Amps When kVA is Known N/A
Kilowatts
Kilovolt-Amps N/A
Horsepower (Output)

Instructions:

Choose the Voltage Type (DC or AC).

From the Values Selection Table, enter the values of the elements of the formula you want.

Click on the Calculate Button.

The answers are shown in the Formula Table above, also the correct formula is displayed according to your element selection.

If DC is chosen then answers will be shown in the DC column.

If AC/1 Single Phase (100s Volt) is chosen then answers will be shown in the AC/1 (115/120) column.

If AC/1 single Phase (200s Volt) is chosen then answers will be shown in the AC/1 (208/240) column.

If AC/ 3 (all Voltages) is chosen then answers will be shown in the AC/3 column.
